Abstract

There is disclosed a video playback device for playing back a video program in fast forward mode on a display screen coupled to the video playback device. The video playback device contains an apparatus for selectively playing back portions of an audio signal associated with the video program during fast forward mode. The apparatus comprises: 1) an audio filtering processor for identifying a plurality of audio sub-segments in the audio signal and determining an importance factor associated with each of the plurality of audio sub-segments; and 2) a video processor coupled to and controlled by the audio filtering processor, wherein the audio filtering processor transmits selected ones of the plurality of audio sub-segments to the video processor and causes the video processor to play the selected audio sub-segments concurrently with a corresponding portion of a video signal from the video program during fast forward mode.
